LM4844 datasheet

The LM4844 is an integrated audio sub-system designed for stereo cell phone applications. Operating on a 3.3V supply, it combines a stereo speaker amplifier delivering 495mW per channel into an 8Ω load and a stereo OCL headphone amplifier delivering 33mW per channel into a 32Ω load.

It integrates the audio amplifiers, volume control, mixer, power management control, and National 3D enhancement all into a single package. In addition, the LM4844 routes and mixes the stereo and mono inputs into 10 distinct output modes. The LM4844 is controlled through an I 2C compatible interface.

Boomer audio power amplifiers are designed specifically to provide high quality output power with a minimal amount of external components.

The LM4844 is available in a very small 2.5mm x 2.9mm 30-bump micro SMD (TL) package.
